It is shown that in close packing of spheres, two types of interstice exist, bounded by six and by four convex spherical surfaces. These are termed ``square'' and ``triangular.'' They are connected by a continuous labyrinth through which a ball not exceeding (2/√3−1)r in radius can be threaded. In both cubic and hexag…

Formulas are derived for the calculation of stress in electrodeposits from the curvature developed in a plated strip. All the formulas are derived from the fundamentals of the theory of elasticity and the relationships among the various formulas are showll. Simplifi ed formulas are derived and their limits of applicab…

The specific heat and thermal expansion of barium titanate ceramics were measured between room temperature and 250°C., and their anomalies were confirmed. The specific heat, that was measured by Sykes' method showed a λ-type anomaly at the Curie temperature, but the magnitude of the anomaly at the peak was considerabl…
